There were no signs that anyone other than suspect in custody was involved in Iowa police shooting, according to a police spokesman.

It appears that the suspect had a recent run-in with police. A 10-minute video posted on YouTube last month by a user calling himself Scott Greene showed an interaction with officers following an incident at a sports stadium.

In the video, a man describes holding up a Confederate battle flag during the playing of the U.S. national anthem, and is heard claiming that he was assaulted. Reuters was unable to immediately confirm whether the video was made by the suspect, whose face does not appear in it.

The suspect, Scott Greene was charged in Iowa in 2001 with assault causing bodily injury and criminal mischief, and the charges were dismissed, according to court records.

In 2014 he pleaded guilty to second-degree harassment and was ordered jailed, records said. Details of the incidents were not immediately available, and it was unclear how long he spent in jail.

Separately in 2014 he pleaded guilty to interference with official acts and was ordered to pay a fine, records said. Details were not immediately available.

Police are searching for 46-year-old Scott Greene, a suspect described as "armed and dangerous" in the ambush-style shootings of two Iowa officers.

ReutersTwo Iowa police officers were shot dead in separate "ambush-style" killings as they sat in their patrol cars early on Wednesday, and police said they were urgently seeking a suspect they consider armed and dangerous.

The campaign announced the cancellation of the Des Moines "get out the vote" event after two Iowa police officers were shot dead in separate "ambush-style" killings as they sat in their patrol cars in the Des Moines area.

A 10-minute video posted on YouTube last month by a user calling himself Scott Greene showed an interaction with officers following the flag incident. A voice, apparently Greene's, is heard complaining to police that "African-American people" took the flag from him in the stands, "assaulted" him, and saying he wanted to press charges.

Police officers shown in the video said he was removed from the stadium because he caused a disturbance in the stands.

The Confederate flag is a racially charged symbol for its association with the pro-slavery South in the U.S. Civil War.

"There were people in the crowd who felt that was insensitive, and that he should be removed from the stadium," Urbandale Police Chief Ross McCarty said.

"You have to understand, in the current social climate that we're in, when you fly the Confederate flag standing in front of several African-American people, that's going to cause a disturbance, OK, whether you intended to or not," a female officer is heard telling the man in the video.

McCarty told reporters that high school officials had banned Greene from their property following that incident, but had been trying to determine exactly how to enforce the ban given that Greene has a daughter who attends the school.
